Best as I can tell, the plain-Jane UA PreCheck invitation doesn't work. However, if you take advantage of UA's offer to pay for a Global Entry interview and you get a Global Entry Pass ID number, you can then insert that in your US reservation and potentially get PreCheck.
Yeah that's what I read. I've been avoiding global entry for civil libertarian reasons, so I'll just have to wait it out in line when flying US.
